I need to know if I have the corporate version of XP Pro installed on my computer if there is any way I can get 9.0c to install. I have tried the version off a game CD, microsoft's website, everything. You see, I had this computer problem with My OS a few months back, well I finally got my buddy out here to fix it, he does so and the compter runs great, but, he used Corporate XP Pro w/sp2 beta to reload, (he got it from thailand but its english version). Anywho, I can't install 9.0c because I guess it reads b or a as c as long as it is any 9.0X. He mentioned a version of Direct X that doesn't check previous versions, any help please?
